NUT(L)-JAM (Komatsu KO01583-12213)

A damaged jam nut can compromise the security of a threaded assembly. During inspection, a loose or missing jam nut may indicate improper torque retention. The jam nut type functions as a secondary fastener to lock a primary nut in place. A concrete failure consequence is that vibration can cause the primary nut to back off if the jam nut is absent or worn. Keeping a jam nut in sound condition helps maintain consistent clamping force on the joint. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO01583-12213. Verify the serial number or application, then call (562) 693-7748.
